HIGH DISCHARGE PRESS – This can occur if the machine’s loading
function is being controlled by a host device such as a sequencer or an
ISC. This warning will occur when the package discharge pressure is
above the maximum offline pressure (rated pressure plus 3 psig (0,2
bar)) for more than 3 seconds. This warning will cause the compressor
to unload. The host device will not be able to load the compressor until
the package discharge pressure falls to the rated pressure of the
machine.
SENSOR FAILURE 4ATT – This will occur if the Package Discharge
Temperature Sensor (4ATT) is missing or broken.

Pressing the STATUS button will display the STATUS screen. The
